Boil the Pasta: Start by bringing a large pot of salted water to a rolling boil over high heat. Once boiling, add the dried spaghetti, cooking according to package instructions until al dente, about 8-10 minutes. Stir occasionally to prevent sticking. Before draining, remember to reserve at least ½ cup of the pasta water, then drain the pasta and set it aside in a large bowl.

Season the Shrimp: In a medium bowl, combine the peeled and deveined shrimp with 2 teaspoons of Old Bay seasoning and 1½ tablespoons of fresh lemon juice. Gently toss to coat the shrimp evenly, allowing them to marinate for about 5 minutes.

Sauté the Garlic and Shrimp: In a large skillet, heat 1 tablespoon of unsalted butter and 1 tablespoon of olive oil over medium heat until melted and shimmering. Add ½ tablespoon of minced garlic to the skillet, sautéing for about 30 seconds until fragrant. Quickly add the marinated shrimp and cook for about 2-3 minutes, or until they turn pink and opaque.

Cook the Shallots and Garlic: Return the skillet to medium heat and add 2 tablespoons of unsalted butter. Once melted, toss in the minced shallots, sautéing for about 2-3 minutes until they become translucent. Next, add the remaining 1½ tablespoons of minced garlic and cook for another 30 seconds.

Deglaze with White Wine: Pour in the ¼ cup of dry white wine, using a wooden spoon to scrape up any flavorful browned bits at the bottom of the skillet. Let it simmer for about 2-3 minutes, allowing the wine to reduce until only 1 tablespoon remains.

Create the Creamy Sauce: Add ½ cup of heavy cream, ½ cup of freshly shredded parmesan cheese, and 1 tablespoon of Old Bay seasoning into the skillet. Stir constantly over low heat until the cheese melts and the sauce becomes creamy, about 2-3 minutes.

Combine the Shrimp and Pasta: Return the cooked shrimp to the skillet, stirring in ¼ cup of chopped parsley for a burst of freshness. Gently toss everything together to ensure the shrimp are coated in the creamy sauce.

Serve and Garnish: With the heat turned off, add the drained spaghetti to the skillet, tossing thoroughly to combine. Taste the Old Bay Garlic Shrimp Pasta and adjust seasoning with additional salt, black pepper, or Old Bay if desired. Serve the pasta hot, garnished with extra parmesan cheese and parsley.
